Title: Catalytic solid-liquid multiphase reactor
Inventor: EHRLING RJUTTER
IPC: C10G2/00
Filed: 1993-02-24
Granted: 1998-10-27
Abstract: FIELD: chemical engineering. SUBSTANCE: reactor is designed for continuous multiphase catalytic reaction, for instance, for production of higher hydrocarbon fuels. Gas reagents are introduced through gasproof plate into suspension, which contains product and finely disintegrated catalyst. Liquid product is separated from the rest of suspension using filter cell enclosing filter element. Over the latter, a pressure drop is produced by the aid of constant-level device inside filter cell, which maintains level of filtrate inside filter cell below suspension level. Suspension is maintained in the continuous- stirring state owing to introducing gaseous components, e.g. steam bubbles. Fluctuations of pressure drop through filter element prevent the latter from clogging. Gas spaces above the filtrate and suspension communicate with one another. EFFECT: facilitated separation of catalyst particles during reaction. 21 cl, 7 dwg, 2 ex

Granted: 1998-03-27
Abstract: FIELD: digital control systems for valve-type converters; three-phase controlled rectifier bridges using microprocessor control systems. SUBSTANCE: primary synchronizing voltage is shaped as difference of any two line voltages across converter input. This eliminates commutation dips in voltage obtained caused by connection of pair of thyristors related to one phase irrespective of control angle. Region free from commutation dips is provided in primary synchronizing voltage obtained; width of this region depends on regulation range of converter control angles. Primary synchronizing voltage obtained is filtered off to obtain final synchronizing voltage. Phase shift of the latter provides for locating zero crossing point in region free from commutation dips. At maximum phase shift of 150 el. deg, regulation range of converter control angle is 0 to 120 el. deg. Minimum phase shift corresponds to sum of maximal control angle and 30 el. deg.
